Xorg doesn't start and some other issues with the RC1 of kernel 6.10

Xorg doesn't start and some other issues with the RC1 of kernel 6.10

[Christian Zigotzky]

Hi All,

Xorg doesn't start anymore since the RC1 of kernel 6.10. We tested it 
with the VirtIO GPU and with some Radeon cards.

Another error message: Failed to start Setup Virtual Console.

Maybe this is the issue: + CONFIG_ARCH_HAS_KERNEL_FPU_SUPPORT=y

Tested with FSL P5040, FSL P5020, and PASEMI boards.

Could you please test Xorg on your PowerPC machines.

Thanks,
Christian

I tested the RC1 in a virtual e5500 QEMU PowerPC machine with Bochs VGA 
(-device VGA,vgamem_mb=256) and Xorg doesn't start either.

Error message: xf86OpenConsole: KDSETMODE KD_GRAPHICS failed 
Inappropriate ioctl for device.

Please test the RC1 with Xorg on your PowerPC machine.

Thanks

That is presumably because of this:

Thx, I already had an eye on this, but thought tracking would not be
needed, as Greg (now CCed) wanted to revert 8c467f3300591a ("VT: Use
macros to define ioctls") two days ago:
https://lore.kernel.org/all/2024052901-police-trash-e9f9@gregkh/

But that commit is not yet in -next afaics. :-/

/me meanwhile wonders if it would be wise to fix this before -rc2

Ciao, Thorsten

Dank u wel![1, 2] And good luck with your studies! Ciao, Thorsten

[1] "Many thx!"

[2] I understand some dutch (more than enough for "geen vrije tijd"),
but do not really speak it; but it was enough to get that simple phrase
right on the first attempt.

Hello Michael,

Many thanks for the hint! :-)

I was able to revert this commit and Xorg works again. We tested it with 
a Radeon and a VirtIO-GPU.

@Skateman
I reduced the uImage. Please test it. Link: 
https://github.com/chzigotzky/kernels/releases/tag/v6.10.0-rc1-4

Have a nice weekend,

Christian
